This is a basic guide to troubleshooting problems with Wifi signal.
I recommend downloading and installing InSSIDer. This free program displays useful information about the wireless networks in your vicinity.
The key fields to look at are:
- This indicates how good the signal is the higher the better. Note that as they numbers are negative -10 is better than -20.
- If you are getting a poor signal i.e. -90 or higher then you should look at boosting the signal either via a repeater or changing the location of the antenna.
- If there are multiple wireless networks in your area look what channels they are on and the signal strength.
- Ideally your wireless network should be set to either channel 1,6 or 11 as these are the only non-overlapping channels.
- If there are other networks on your channel then change you wireless to a “free” channel
- If you have multiple access points broadcasting the same SSID with overlapping signals then I recommend they are put on different channels (e.g. 1 access point on channel 1, the other on channel 6)
